Broken out-of-the-box on MacOS MBP M5 Max - Harper highlights do not align with words. Cannot trigger popups.

**Describe the bug**
I have a brand new MacBookPro M5 Max, running Tahoe 26.5.1 (25F80) and Harper Version 2.6.0 (2.6.0). I have preformed a fresh install of Harper.

When working through the Getting Started steps, I have launched TextEdit and attempted to follow instuctions:
`Open TextEdit, type "its not alot of fun", and watch Harper underline the mistakes.`

In TextEdit and other apps, the Harper highlights do not align with words. They appear very low and almost offscreen. I am unable to click on these highlights to get the Harper modal windows.

**To Reproduce**
Steps to reproduce the behaviour:

1. Perform a fresh install of Harper 2.6.0 on MacOs Tahoe
2. Attempt to follow firsttime instructions
3. Note the observed behaviour in TextEdit and other apps

**Expected behavior**
Harper should function as designed

Start by reproducing the issue in TextEdit and another macOS application using Harper 2.6.0 on macOS Tahoe 26.5.1, following the Getting Started steps. Compare the highlight position with the underlying words and whether the highlights accept clicks for the Harper popups; done means alignment and popup interaction work as expected.
